3.3.2 Changing the Run Level

Use the telinit command to change the system run level, for example:

# telinit 1

which place the system in single-user mode.

Tip

telinit 0 halts a system immediately.

telinit 6 reboots a system immediately.

You can also use the init command to change run level. Any instance of init that does not have a process ID of 1 invokes telinit to change the run level.

For more information, see the telinit(8) manual page.
